Thomas KP Lee: The key feature of 1/2000 flash syn speed on the new XCD lenses is definitely a winner in action portrait application, but most other applications will not need such high speed syn, so only limited quantity of such new leaf shutter lenses will be bought, while a lot of users will try to use old and existing mid format lenses!

It is true, but do not need every lenses to have such high speed syn is my point, perhaps a lens of 80/2.8 and 110/2 will be enough, it is not necessary to use such for landscape or long tele for sport or wild life!

There are rumors that Fuji and Sony will also announce mirrorless mid format camera later on this years, whoever able to win in the market place is the one that are able to have the most adapters to use other / older mid format lenses, just like in the case of Sony E ( of FE) mount. Hasselblad even being the first one to come, but if the mount is limiting itself to the 43.8 x 32.9mm sensor, not for any larger sensor, while a lot of old mid format lenses can cover the full size 60 x 45mm for the future digital sensors. Perhaps Hasselblad wishes user to buy new lenses! While Fuji or Sony ( definitely will define their own mount!) if able to cover larger size sensor and able to have more third parties adapters to produce various adapters and with feature to help manual focus and/or auto focus, then Hasselblad will still lose in the battle!

I did not see anyone compare this lens to the Zeiss Contax G Planar 45mm f2 lens, which I have been using on my A7r since the third party autofocus adapter has been available. The G45 is much smaller and inexpensive (around $300 2nd handed), while at f2 it is still very sharp, although the third party adapter does not autofocus fast ( takes more than 1 sec to do the autofocus) and is only AF-S, but for not fast moving objects, the combination works OK. It seems the G45's planar design is very good if it can be duplicated on an modern autofocus mechanism and sell at lower price!

Still disappointing that it does not have Wi-Fi and let Focus have a iPad / Androd version such that it can get live view on an iPad / Androd notepad, such that manual focusing when using the tilt/shift adaptor is easier, and more portable. I will keep my H4D-40 and wait further.

Timmbits: " it’s better to change the focal point by moving the lens physically back and forth rather than using the focus ring"

I am curious as to how to do this...

I'm imagining my camera on a tripod, and I have to move it by a fraction of a millimeter... how does that work?

Usually I am using three dimensions gear head when doing such macro photo, it n get very fine movements easily.
